The XM314 series is designed to detect both flammable and toxic gases using multiple advanced detection principles, including Catalytic, Electrochemical, Infrared, and Photoionization Detector (PID) technologies.
The gas detector is built to handle harsh conditions, featuring an IP67 protection grade and an explosion-proof certification rating of Ex db ia IIC T4 Ga. Its housing is constructed using anti-static TPU soft rubber and anti-static PC hard rubber.
The detector is equipped with a triple-alarm system: a highly audible alarm generating sound levels of ≥90dB @ 0.3m, an LED light alarm, and a vibration alarm to ensure warnings are noticed immediately.
Diffusion models (such as XM311, XM312, XM313, XM314) measure gases present in the immediate surrounding air. Pump-suction models (such as XM311BCGT, XM312BCGT, XM314BCGT) actively draw air into the sensor, which is ideal for sampling confined spaces or remote areas.
The first digit of the model number indicates the maximum number of sensors supported (e.g., XM311 supports 1 sensor, while XM314 supports up to 4 sensors). Suffixes denote specialized features: "CGT" indicates built-in 4G, GPS, and Gyroscope modules, while "J" indicates compatibility with a Gooseneck Tube.
The device performs comprehensive self-diagnostics to verify operational readiness, monitoring low battery status, calibration prompts, remaining sensor life, sensor failures, calibration signal lock, register memory levels, air pump blockages, and air pump leakage.
